Paul is correct.
In short development enviornment means we develop our code to obtain desired result by design, coding etc.
Once we developed our code then we make our code ready to use to obtain desired results that is known as deployment enviornment like testing application performance.

Deployment Environment then you need to copy the same files(with directories(slight change)) to the deployment directory that is under the web container directory...

I'd say both of those were a development environment. A deployment environment is a test or production enviroment (as Ninad mentioned earlier).
